I finally took some time to try these examples. I'm impressed. Also interesting that you've implemented this version in a browser. Will the version that is available for the PC-1 run in a browser or will it be a standalone IDE?
Are there plans to support compiling programs so they can run outside of an IDE?
Yes, there are plans to allow compilation to the various platforms. It is based on Cordova, so, potentially you can compile your app for almost any platform (Android, iOS, Linux, Windows, MacOS).
